In the following we will outline our findings related to the four dimensions of distributed collaboration according to Olson and Olson [1]} namely common ground (section REF ), coupling of group work (section REF ), collaboration technology readiness (section REF ) and technology readiness (section REF ). In addition we will elaborate on aspects that are specific to collaboration in hackathons and that are not common for collaboration in work-related contexts (section REF ). Under these lenses we discuss how teams collaborated focusing on team formation, task assignment within a team, a team's collaboration approach and the technologies they used (RQ\(_{\ref {RQ1}}\) ). Moreover, we discuss the potential influence of event design on team collaboration focusing on an event's agenda, mentoring and the tools provided by the organizers (RQ\(_{\ref {RQ2}}\) ).
